4”Z1W/S CORE DRILL

MACHINE COMPONENTS

Ø The main components of the 4”Z1 are the spindle, gearbox and motor. The drilling

rig consists of a carriage, stand and base. The spindle is driven by the transfer case

and motor.

o These components must be not be removed except by a qualified technician.

Power must be disconnected prior to any service.

o If using the drilling rig, this machine has one primary adjusting point for the

travel between the drill carriage and the drill stand. The main way to increase

or decrease the users ability to move the drill by hand is with this system.

These are the black hex bolts on the side and back of the machine that have a

locking nut around them. These are generally used to tighten up the travel as

the slides wear over time. Be mindful to evenly adjust these so that the travel

is even and smooth. The ideal travel generally keeps the drill in place when

the user is not using the drill (this is usually on the tighter side) although

individual users needs may vary. The side black carriage bolt can also be

used for temporarily locking the carriage in place.
